Abstract

A photocatalyst laminate which is composed of an undercoat layer provided on a substrate and a photocatalyst layer laminated on the surface of the undercoat layer. The undercoat layer contains (A) 100 parts by mass of a resin component and (B) 0.1-50 parts by mass of fine core-shell particles, each of which has a core that is formed of a fine tetragonal titanium oxide solid solution particle wherein tin and manganese are solid-solved and a shell that is formed from silicon oxide on the outside of the core. This photocatalyst laminate is not susceptible to decrease in the photocatalyst function even under outdoor exposure for a long period of time, and is thus capable of providing a coated article that exhibits excellent weather resistance.
